Jesús Gómez Portugal Wastewater Treatment Plant, Aguascalientes, Mexico

The Jesús Gómez Portugal wastewater treatment plant is located in Jesús Gómez Portugal (Margaritas), a locality within the municipality of Jesús María, Aguascalientes, Mexico. It serves a population of approximately 9,127 people, classifying it as a small to medium agglomeration under Mexican wastewater regulations. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Mexico under the NOM-001-SEMARNAT-1996 standard. With a designed capacity of 1,598.40 m³/day and an average discharge volume of 864.00 m³/day, the facility operates below its full capacity, indicating potential for future growth. The treated effluent is discharged into the local hydrological system, which ultimately drains into the Río San Pedro, part of the Lerma-Santiago-Pacific basin. This river system supports agricultural irrigation and local ecosystems, making the plant's treatment performance important for downstream water quality and environmental health.

The plant discharges into the Río San Pedro, a tributary of the Lerma River, which flows into Lake Chapala and eventually the Pacific Ocean via the Río Grande de Santiago. The Lerma-Santiago basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and human consumption. Proper secondary treatment helps reduce nutrient and pathogen loads, protecting downstream ecosystems and water users.
